Coppergrass

This big, copper grass grows up to 6 feet (1.8 meters) tall. The stiff, pointed stalks grow in extensive patches that are resilient and they spread and grow quickly.

When mature, the end of the stem eventually transforms into a giant, cream flower.

During the mid-autumn, it produces very little pollen, but can cause severe allergic reactions, and after flowering, it is left with lots of medium-sized grains.
